越来越多的公司正在实施全面的回收和再制造计划。这些努力通常涉及联合制造和再制造系统的操作。管理这种混合系统的主要挑战之一是产品回报的随机性。特别是，回报的条件有很大的差异。本文提出了一种基于质量的退货产品分类的影响评估方法。通过对连续时间马尔可夫链模型的广泛数值研究，我们表明，将返回的产品质量的再制造和处置决策可以导致显着的成本节约。我们发现，这些储蓄被放大的回报质量下降，并作为回报率增加。我们还表明，在再制造中优先考虑更高质量的回报，一般来说，是一个更好的策略。
An increasing number of companies have been implementing comprehensive recycling and remanufacturing programs. These endeavors typically involve the operation of joint manufacturing and remanufacturing systems. One of the major challenges in managing such hybrid systems is the stochastic nature of product returns. In particular, there is significant variability in the condition of the returns. This paper presents an approach for assessing the impact of quality-based categorization of returned products. Through extensive numerical studies on a continuous-time Markov chain model, we show that incorporation of returned product quality in the remanufacturing and disposal decisions can lead to significant cost savings. We find that these savings are amplified as the return quality decreases, and as the return rate increases. We also show that prioritizing higher quality returns in remanufacturing is, in general, a better strategy.
